CONSTRUCTION OF BOATS- Specification of Letters Patent.

Patented Oct. 2, 1906,

Application filed January 5, 1906. Serial No. 294.740.

To all whom it may concern:

Be it known that I, BENJAMIN CART- WRIGHT TUTI-IILL, a citizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in the Construction of Boats, of which the following is a specification.

My invention is an improvement in the construction of boats; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and shown.

The planking of a boat is usually connected to the frame by means of a nail or rivet passing through the plank and frame and riveted or clenched on the inner side. I employ 'a wire or rod on the inner surface of the frame in conjunction with the nail or rivet and over which the nail is clenched by means of a grooved set, die, or band held firmly against the frame while the nail or rivet is being driven. By this construction the wire serves the purpose of a bur and obviates the necessity of riveting the nails after they have been driven, as is now customary to secure firstclass workmanship.

Referring to the accompanying drawings, Figure 1 represents a section of a boat being constructed over molds. Fig. 2 shows a section taken along the line p p of Fig. 1. Fig. 3 is a detail view of a set or die for clenching the nails when the boat is not constructed over molds, as in Fig. 1. Fig. 4 is a modification of Fig. 3.

In constructing a boat by the use of my improved construction the boat is built in the usual manner, except the wire f is first placed along the inner surface of the frame a before it is bent and fitted into place over the mold a a, the outer edge of which is covered by the grooved metal band 01. The fastening or nail 6, connecting the plank b to the frame 0, being driven strikes the groove h of the metal band d and is deflected or bent over and around the wire f until the point again enters the wood on the opposite side, thus securing the plank b and the frame 0 together in a most eflicient manner.

Fig. 3 shows a set or die for use in clenching the nails when the boat is not constructed over molds or forms, as in Fig. 1. The face has a groove 7L, and the clenching is done in the same manner as stated above.

Fig. 4 shows a set or die similar to that shown in Fig. 3, except the notch or groove h extends across the tool and the wire f is in short lengths and extends across the grain of the wood of the frame 0. The wire is held in place by the notches 70 7c, and the clenching is done in the same manner as before stated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination in a boat of the planking, the frame, a wire or rod at the inner side of the frame and a nail clenched around said wire or rod substantially as set forth.

2. The combination of the planking, the frame, a wire or rod on the inner side of the frame and a nail or rivet driven through the planking and frame and clenched around the wire or rod, substantially as shown.

3. The combination of the planking, the frame, a Wire or rod on the inner side of the frame extending in the direction of length of the frame, and a nail or rivet driven through the planking and frame and clenched around the wire or rod substantially as set forth and described.

4. The combination of the planking, the frame, a wire or rod on the inner surface of the frame, in short lengths or clips and a nail or rivet driven through the planking and frame and clenched around the wire or rod substantially as described and for the purposes set forth.

In testimony whereof I affix my signature in presence of two subscribing witnesses.

BENJAMIN CARTWRIGHT TUTHILL.
